The pro-government Sabah newspaper published photos of a man it claimed to be someone who travels with the Saudi crown prince.
The Washington Post has previously cited unnamed U.S. and Turkish officials pointing to audio and video recordings that supposedly prove Khashoggi was killed inside the consulate and was then dismembered.
The journalist's disappearance has resulted in global pressure on Saudi Arabia, the world's largest oil exporter.
Treasury Secretary Steve Mnuchin will not attend the Future Investment Initiative summit in Riyadh, Saudi Arabia, as questions linger about what happened to journalist Jamal Khashoggi, Mnuchin and White House press secretary Sarah Sanders announced on Twitter Thursday.
"The conditions have not yet been met for me to go to Riyadh", Le Maire told French television's Public Senat.
The Crown Prince told Pompeo that the United States and Saudi Arabia "are strong and old allies".
The US president has been on the defensive ever since Khashoggi - a US resident and Washington Post contributor who had criticised Prince Mohammed - vanished on Oct 2 after visiting the Istanbul consulate.
Trump and Pompeo also stressed America's close ties to the Saudis ― and the massive amounts of money that the USA receives from the kingdom.
US President Donald Trump acknowledged Thursday it "certainly looks" as though missing Saudi journalist Jamal Khashoggi is dead, and he threatened "very severe" consequences if the Saudis are found to have murdered him. "The facts are serious and we want to know the truth", the minister said.
Khashoggi, a Saudi national, was last seen entering the Saudi consulate in Istanbul to get paperwork for a marriage to a Turkish fiancée.
He added: "It sounded to me like maybe these could have been rogue killers".
President Donald Trump is facing increased pressure from Congress over his handling of Khashoggi's disappearance, exposing a widening rift between the White House and Capitol Hill over the USA relationship with Saudi Arabia. For at least the past week, evidence that Saudi Arabia bore responsibility for Khashoggi's fate has been plentiful, considering that he entered the Saudi Consulate in Istanbul on October 2 and hasn't surfaced since.
